Title: Improvements relating to disc brakes for vehicles
IPC: F16D55/2255
Filed: 1963-04-10
Abstract: 978,386. Disc brakes. DAIMLER-BENZ A.G. April 10, 1963 [April 12, 1962], No. 14381/63. Heading F2E. A disc brake for vehicles comprises a disc 15 secured in the region of its outer periphery to the wheel 10 to be braked, an axially movable caliper 20 which embraces the disc from the inside and whose arms carry brake pads 21, 22 and whose operating members are located one side only of the disc. The caliper is carried by a non-rotating part 16 of the vehicle and has the form of a double fork whose legs embrace both the disc and the pads in such a manner that each pad bears on each side with at least half its side surface against one of the legs. As shown, the brake carrier 16 is secured to a part 13 of the axle carrier and extends upwardly into a double fork whose two pairs of legs 18, 19 lie on the inner and outer sides of the disc respectively. The U-shaped caliper 20 carries square pads 21, 22 which are closely embraced by the legs of the forks 18, 19 and is axially movable in a slot 29 in the carrier 16. A spring 31 presses the caliper against the bottom of the slot 29 and allows the caliper and pads to adjust themselves relative to the disc. Pistons 25, 27 attached respectively to the caliper and pad 22 and disposed in a floating cylinder 26 apply the pads against the disc on introduction of brake fluid at the middle of the cylinder 26. Hand-operation of the brake is by means of a rod 37 which sealingly penetrates the piston 25 to bear against the piston 27 with a mushroom head 38. At its outer end the rod abuts an adjustable plug 40 on a lever 24 pivoted to the caliper. A Bowden cable sheath 43 abuts the lever 24 and the core of the cable is attached to the caliper so that on pivotal movement of the lever 24 the pads are applied against the disc. Since angular deviations may occur between the wheel shaft and the wheel mounting, the bearing 12 for the axle 11 is supported by its outer race in a ring 46 of rubber or like resilient material. Alternatively the outside of the bearing may be of partspherical shape. In another embodiment wherein the axle is secured to the axle carrier and the wheel is rotatable on the axle two separate fork pieces are secured by screws to the axle carrier to form a double fork and the cylinder 26 is secured to one arm of the caliper 20.
